WINDOW-CONTROL MECHANISM.

application momm 9, 1921. Serial '1... 467,910.

This invention relates to window control mechanism, and more particularly to con trolling means for vertically shdable w1ndow members such as are commonly employed on motor vehicles.

It is the object of the invention to provlde a control mechanism for a sliding wmdow member which is adapted, in its open position, to enter a chamber adjacent the window opening, which mechanism will be actuable by a handle slidable transversely of the direction of travel of the window member and which projects from said chamber in all positions of adjustment.

A further object of the invention 1s to provide a mechanism of the character described that will be irreversible and will require a comparatively slight muscular effort in exercising control.

In the drawings:

Figure 1 is an interior view of a motor vehicle door partially broken away to disclose the control mechanism chambered in said door;

Figure 2 is a similar enlarged view of this mechanism;

Figure 3 is a fragmentary vertical section on line 33 of Figure 1 showin the means constraining the actuating han 1e torectilinear movement.

Figure 4: is a fragmentary edge view of the driving gear segment.

In these views the reference character A designates a motor vehicle door having in its upper portion the window opening B and provided with a closure for said opening, having the nature of a vertically slidable glass plate C, which in its lowered or opened position is adapted to enter a chamber D formed in the lower portion of the door. Within said chamber a control arm E is pivoted at one extremity upon a bracket F secured to one of the side uprights of the door and carries upon its other end the roller G engaging beneath the plate C. To the pivotal end of said control arm there is secured a segmental bevel gear H with which is enmeshed a driving pinion I upon a shaft I. Said shaft is journalled in a pair of bearings I integrally formed upon an arm J mounted upon the bracket F co-pivotally with the control arm E. Upon itsouter end the shaft I carries a helical pinion K enmeshed with a segmental helical gear L journalled upon the free'end of an upward terminal extension M of the arm J. The gear L 1s adapted to be rocked by a handle N connected-to said gear by a pair of rods 0 symmetricall disposed ateach side of the center line of the gear and handle and extending divergently from the handle to the gear. Upon the handle N is mounted a ballheaded pin P, the head of which is slidably engaged in a sheet metal channel Q, formed preferably from a single strip of folded sheet metal and secured between the sill 'R of the window and the finish stri S of said sill. Said channel stri exten s substantially the full Width of t a window opening and is transversely curved to conform to the shape of the-ball head of the pin P, (see Flgure 3) embracing said head sufiiciently to retain the same from disengagement. 1

- In the operation of the described mechanism, the handle G is constrained to'travel 1n a rectilinear line transverse to the direction of travel of the window member and when thus actuated said handle both rocks the gear L and shifts said gear together with the free end of the arm J bodily up- Ward or downward according to the direction of travel of the handle. Rocking of the segment L rotates the pinion K and shaft 1 and rotation of said shaft acts through the gears H and I to rock the control arm E. The pitch of the helical teeth of the pinion K and gear L is such as to provide a lock against a reverse drive, and consequently the sliding window lmember must remain stationary in any position of adjustment. counterbalancing means for the sliding window member consisting of an arm T piv: oted at one end upon the opposite upright to that which carries the bracket F and bearing upwardly at its other end upon the sliding window member, said arm being upwardly urged by the coil spring U.

What I claim as my invention is:

1. In a window control mechanism, the
